Reply to Flambaum Commentary [arXiv:0808.2518] on Black Hole Constraints on Varying Fundamental Constants [arXiv:0706.2188, PRL 99, 061301 (2007)]

TL;DR

This paper responds to Flambaum's critique regarding the use of thermodynamics to set bounds on changing fundamental constants like the fine structure constant.

Contribution

It clarifies and defends the application of the Generalized Second Law of Thermodynamics in constraining variations of fundamental constants.

Findings

Reaffirms the validity of thermodynamic limits on constant variation

Addresses and counters Flambaum's commentary

Supports the original constraints derived in prior work

Abstract

We discuss the Flambaum commentary [arXiv:0808.2518] on the application of the Generalized Second Law of Thermodynamics to derive limits on the variation of fundamental constants, for example the fine structure constant.
